Question

If the resonance curve is very sharp, then the bandwidth is​

Answer 1

Answer:

The Q factor of a resonance circuit is given as

Q=

R

ω

0

L

where ω

0

=

LC

1

is the resonant frequency

Example: The values of L,C and R in an L−C−R series circuit are 4mH,40pF and 100Ω respectively. The quality factor of the current is

R

1

C

L

=100
